Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00105 | $0.01216 |
| Opus 5.5 | $0.00042 | $0.00486 |
| Sonnet 5.5 | $0.00021 | $0.00243 |
| Haiku 4.5 | $0.00011 | $0.00122 |
Grade A, and why
codebase-mapper scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Codebase Mapper Knowledge Base
Purpose
Generate a human-readable project guide for unfamiliar codebases. Output is narrative, didactic material - not technical dumps or AI-oriented analysis. Target audience: a smart colleague on their first day.
Output Structure
All output goes to .codebase-map/ in the project root:
.codebase-map/
INDEX.md # Entry point with navigable summary
00-executive-summary.md # Plain-language summary for anyone (non-technical)
01-overview.md # What is this project, who is it for
02-features.md # Functional capabilities
03-tech-stack.md # Technologies and dependencies
04-architecture.md # How code is organized, layers, components
05-workflows.md # Main user/system flows with diagrams
06-data-model.md # Data structures, entities, relationships
07-getting-started.md # Where to start working, key files, dev setup
08-open-questions.md # Gaps, unknowns, things to ask the team
09-project-anatomy.md # Config files, env vars, scripts, directory tree
10-configuration-guide.md # Configuration recipes, operations, troubleshooting
11-glossary.md # Domain and technical glossary (plain definitions)
_internal/
context-brief.md # Phase 1 exploration output (internal reference)
interconnect.md # Phase 1b structured map: contracts, invariants, domain rules (optional)
Core Principles
Tone
- Narrative, conversational, didactic
- Write for the audience in the Project Profile (see references/audience-adaptation.md); default to a smart colleague on their first day when no profile exists
- Progressive disclosure: big picture first, then details
- Honest about gaps - never fabricate or speculate
Content Rules
- Every technical term gets a brief inline explanation on first use
- File paths always included - reference actual code paths for every claim
- Diagrams inline - Mermaid blocks embedded in documents, not separate files
- No AI boilerplate: no "In this document we will...", no "Let's dive in", no trailing summaries
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

codebase-mapper is a skill published in the GitHub repository acaprino/daodan (9 stars, last pushed today), licensed MIT. It adds 105 tokens to every session and 1,216 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
